Thanks in advance for the help :)
1. What is the maximum height of a bullet shot from a gun at 150 m/sec at a 5.0 degree angle?
2. In order to measure the acceleration due to gravity on the moon, an astronaut fires a projectile from a launcher. The initial velocity is 57.0 ft/sec at 22.5 degrees and the projectile's range is measured to be 220.0 feet. What is the gravity on the moon as calculated by this data? Provide your answer in units of feet and seconds.
3. A submarine travels at 18.0 mph for 92.0 minutes at 90.0 degrees. Then the sub adjusts its course, traveling at 16.0 mph for 2.25 hours at 155 degrees. What is the sub's resultant vector? Units of miles and hours should be used to solve this problem.
4. What is the range of a gun that fires its bullets with a velocity of 175 meters per second at an angle of 30.0 degrees? Assume the bullets land at the same height from which they were launched. Use units of meters and seconds to solve this problem.
5. Aimed at an angle of 45 degrees, a cannon has a range of 4,123 feet. What is the initial speed of a cannonball launched from this cannon? Assume the cannonballs land at the height from which they were launched. Use units of feet and seconds to solve this problem.
6. A stuntman was prepared to jump a river in a car. From the base of a 33.0-foot cliff to the other side of the river was 113 feet. How fast should his initial velocity be in order to clear the river and what is the y-component of his velocity right before he hits the ground on the other side of the river? The ground leading up to the cliff edge is level and no ramp is being used. Use units of feet and seconds to solve this problem.
7. A hiker follows a trail map with the following instructions on how to get to a waterfall: Travel with a constant velocity of 2.1 meters per second at a heading of 120.0 degrees for 1.1 hours, then turn to a heading of 200.0 degrees and travel at the same speed for 2.3 hours. What will the hiker's final displacement be? Calculate your answers using units of meters and hours.
Please show work and answer as many as possible! Thank you

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
